Mickey Mouse + Magic Mouse = Mighty Steve

Is it better to have a lot of something good or a little of something great? If Apple CEO Steve Jobs is any indication, it's better to have both.

In September, Alpha Steve had an estimated personal net worth of $5.1 billion, enough to end up the 43rd richest person in the U.S. according to Forbes' list of the 400 richest people in the states. This week he's up to at least $5.4 billion. If you think that's because of the tear on which Apple's stock has gone over the past few weeks, you're only a little over half right.

According to filings by Apple (AAPL), Jobs owns 5.426 million shares of Apple stock. As of Tuesday night, Apple's stock had picked up 26.39 points since Forbes' counted the 400 "haves." Jobs shares had gained $146 million in value. Not bad.

Disney (DIS) filings say Jobs owns 138 million shares of the happiest company on Earth. Those shares have not had nearly the run enjoyed by Apple shares over the last few weeks, gaining only 99 cents as of Tuesday night. Still, Jobs has so many of them that they've increased in value by $136 million. Not bad either.
